Joe's thoughts on this product - "When compared side by side to a standard 600 watt HPS lights, you can see that these Gavita Pros are a lot brighter & the ballast is considerably cooler than standard HPS lights. They are really well made, you can tell that Gavita have put a lot of thought into all aspects of production, you can see why the majority of commercial growers throughout the world will only use Gavita lights."

How the Gavita Pro Grow Light Works:
The output colour spectrum of this grow light:
The black line in the graph above represents the "McCree Curve", which gives a relative indication of how efficiently a plant uses the different colours in the light spectrum to photosynthesise with.
Used by the grow industry, Professional 400 Volt HPS lamps have a number of key benefits which makes them superior to standard HPS lamps – even ones being run from top-quality digital ballasts.
A 400 Volt HPS lamp is much more efficient than a standard HPS lamp. Both systems consume 600 Watts and therefore cost exactly the same to run but the Pro HPS lamps run at a higher voltage and a lower current. 400 Volt Pro HPS lamps produce more light for the same power consumption and will give at least 10% higher yield compared to even the best standard HPS systems. In fact, when they are seen side-by-side, the HPS lights are noticeably brighter, run cooler and the light they produce is slightly whiter. So in addition to them giving a higher yield, plants grown under a 400 Volt Pro HPS are healthier, happier and are at less risk of heat damage too.
The way that the Gavita Pro HPS lights works is that UK mains power (230 Volts) is fed directly to the combined ballast and reflector via a standard mains power lead. The special ballast then converts the mains electricity to drive the special 400 Volt / 600 Watt lamp. The distance from the ballast to the lamp is very short, meaning that virtually no power is lost through the connecting cable. The reflector has been especially designed to give a superbly even light spread despite it's small size. The surface of the reflector has one of the best coatings available and gives at least 95% reflectivity.
400 Volt / 600 Watt Pro HPS lamps maintain their efficiency and light output for much longer than standard HPS lamps. In fact they will normally last at least a year before they need to be changed out. It should be noted that normal HPS lamps and 400 Volt Pro HPS lamps are NOT interchangeable with different ballasts. Standard HPS lamps should only be used with standard or digital 230 Volt ballasts. 400 Volt Pro HPS lamps should only be used in lighting systems with a 400 Volt Pro HPS ballast like with this Gavita Pro product. 400 Volt Pro HPS lamps can be identified by the HPS EL marking on them.
How to Use the Gavita Pro Grow Light:
Simply hang the combined ballast & reflector over the centre of the grow-space at an appropriate height using easy rolls or jack chain. Holding your lamp with a clean cloth insert the 400 Volt / 600 Watt Pro HPS lamp into the E40 bulb-holder in the reflector and screw it in very firmly. Run the 5m lead from the reflector to a standard UK mains outlet or your contactor and switch on.
Gavita recommends that the reflector is changed regularly to maintain garden efficiency because the reflectivity of the surface does degrade a little over time. We would recommend every 1-2 years.
Warning 1: When it is time to change out the lamp, make sure that it is replaced with another 400 Volt / 600 Watt Pro HPS lamp such as the Philips Greenpower 400 Volt / 600 Watt HPS EL. Using a standard HPS lamp in a 400 Volt lighting system will possibly cause damage, explosions or fire.
Warning 2: When HID lamps are switched on they run extremely hot. As with all high pressure sodium and metal halide bulbs it is necessary to avoid touching the lamp with anything such as fingers or plants as this may cause severe burns or fires. In particular avoid sprays or liquids coming into contact with the lamp as this may cause premature failure or even an explosion.
